Abstract	Thermoelectric nanomaterials offer significant potential for sustainable energy conversion by enabling direct transformation of waste heat into electricity. This manuscript presents a comprehensive simulated experimental analysis comparing bulk and nanostructured materials. Parameters including Seebeck coefficient, electrical conductivity, and thermal conductivity were evaluated to calculate the figure of merit (ZT). Nanostructured samples demonstrate superior performance due to reduced thermal conductivity, enhanced Seebeck coefficient via quantum confinement, and maintained electrical conductivity. Detailed discussion on phonon scattering mechanisms, interface engineering, and potential applications in waste heat recovery and green energy technologies is provided. The expanded analysis emphasizes the importance of nanoscale engineering in optimizing thermoelectric materials for practical energy conversion
